STEAM-WHISTLE SPECIFICATION forming part of Letters Patent No.`511,490, dated December 26, 18.93. Applicauwmea september so', 189x. sena No. 447.387. (Nomoam To @ZZ whom t may conoew. l

Be it known that I, FRANK M. ASHLEY, a citizen of the United States, residing at Hawthorne, county of Passaic, State of New Jersey, have invented certain new and' useful Improvements in Steam-Whistles, of which the following is a specification.

' and more particularlypointed out in the claims appended hereto.

Referring to said drawings, Figure I represents a vertical section of .one form of my improved steam whistle. Fig. II represents the same form with a slight modification of the base or supporting piece. Fig. III represents my improved steam whistle with an enlarged bell or sounding chamber. Figs. IV, V and VI are vertical sections of otherforms. Fig. VII is a cross section on the line d a, Fig. V. Figs. VIII and IX are vertical sections of other forms of my improved steam whistle. Fig. X is a side elevation of the form shown in Fig. IX. Fig. XI is a cross section on the line bh, Fig. IX.

In the drawings,Arepresents a base piece. In Fig. I,I have shown the base piece having a cap B formed separately therefrom and adjustable by means of screw joint O to the base piece A.

In Fig. II, these parts are reversed, the cap B screwing inside instead of outside of the base piece A. The result however is the same in both cases and the annular opening D to permit the egress of the steam is provided between the rim of the cap B and the edge of the annular base piece A. In these forms, the cap B extends upwardly andis provided with supporting pieces E formed integrally therewith. These branches are made of more or less resilient metal, are four in number and are independent of each other and terminate at their upper ends in heads F upon the exterior surfaces of Iwhich are screw threads'f. These screw threads intermesh with screw threadsg upon the integral surface of the bell G.

In Fig. III, I show an enlarged bell chamber, theupper portion being of greater diameter than the lower portion. `In this case also the base .piece A is formed in one with. the cap B and the supporting branches E are constructed independently of the base A. This construction is also shown in Fig. IV. In this form however I use a straight up'and down bell instead'of the enlarged bell chamber.

In Fig. Vthe branch supports E are formed integrally with the bell Gr and the latter -is provided with exterior screw threads g which intermesh with corresponding threads h upon the supplementary bell rimH.

In Fig. VI,I show the bell chamber provided with four legs or branches E but instead of curving` to a central or common point; they extend straight down and are 'screw jointed to the base A.

At K in Fig. VI, I showa depending rim on the inside of the bell which is subdivided into several portions so as to give the proper vibratory eect.

Fig. VIII is another modification, the supporting arms E being inserted in the base A and extending upwardly and outwardly and being attached integrally to the bell G. In

this case I utilize a' rod or' spindle S which is screw jointed with the baseA and which provides for attachment of the bell to the base and for adjustment thereto. This ideais further modiiied in Figs. IX, X and XI where thebellis supported on the sides by means of the branch arms E and isheld in place by means of spindle or rod S.

In all these forms I show the branch arms variously constructed, all of them however being capable of being utilized as strengthening brackets and supports for the bell and extending to the outer ri m`of the bell.

A feature common to the various constructions shown, is the arms a, which strengthen and support the cap B of the base piece A.

Having thus .described my invention, the following is what I claim as new therein and desire to secure by Letters Pat-ent:

ICO

l. In steam whistles the combination of a extending from the periphery of the bell at a point between its outer and inner ends, to the support.

2. In steam whistles, the combination of a base, a bell made adjustable relatively to the base and provided with branch supporting arms that extend from a point between the ends of the bell to the base, as and for the purposes set forth.

3. In steam whistles, the combination of a bell and its support with compressible and resilient branch supporting arms screw jointed with the bell and carried by said support as and for the purposes set forth.

4. In a steam whistle, the combination of a base, a bell chamber, branch arms extending from the base to the periphery of the bell chamber, the lower part of the bell projecting below the junction of said arms with the bell and means for adjusting the said chamber relatively to the base.

5. In a steam whistle, an adjustable bell chamber having parallel vertical sides at the lower end andan enlarged chamber at its upper end combined with branch pieces E extending from the periphery of the bell at a point between its outer and inner ends, as and for the purposes set forth.

FRANK M. ASHLEY.
